Abstract
A SOC correcting system in a parallel structure of multiple packs in which a plurality of sub-packs having serially connected cells are connected in parallel. The system includes sub BMSs connected to each of the sub-packs a main BMS connected to each of the sub BMSs to collect the SOCs calculated in each of the sub BMSs and to transmit a final SOC to a vehicle SOC to a vehicle controller. When an average SOC to each SOC of the sub-packs is less than 50%, the main BMS determines a minimum value among the SOCs of the sub-packs as a final SOC, and when the average SOC to each SOC of the sub-packs is 50% or more, the main BMS determines a maximum value among the SOCs of the sub-packs as a final SOC.
